5 Signs You Need a New Roof

Most homeowners take their roofs for granted – until they spring a leak. Maintenance and repair can help extend the lifespan of a roof, but eventually, it will have to be replaced.

How can you tell whether you need a repair or a replacement? A professional roofer can give you a definitive answer, but you can also be on the lookout for these five signs that it’s time for a new roof.

1. Your Roof Hasn’t Been Replaced in Decades

How old is the roof? Check your home improvement records to see how long ago the roof was replaced or reshingled. Knowing the date of the installation and the material will give you some insight into how much life your roof has left.

In general, a typical roof should be replaced every 20-25 years. The longevity of the roof will also depend on whether you only have one layer of shingles and if it’s properly ventilated.

If your roof is more than 20 years old, and it was installed over another layer (or multiple layers) of shingles, it should probably be replaced.

2. Your Shingles Aren’t Laying Flat

Check your shingles (carefully and safely) to make sure that they’re in good condition, especially after a heavy storm.

Shingles should lie flat against your roof. If you find patches that are damaged, cracked, curled or buckling, repairs may be required. Dominion Roofing of Markham, Ontario explains that any damage to a roof must be quickly addressed to prevent extensive damage to the roofing materials and structure. If a storm or other disaster has caused extensive damage, replacement may be the best option.

Missing shingles is another major sign that your roof is failing.

Ideally, you should have a professional roofer check the status of your shingles. A roofer will know what to look for, how to safely inspect your roof, and will have the right tools for the job.

3. Your Shingles are Losing Granules

If your shingles are losing granules, this is another sign that the singles may be past their life expectancy.

Check your gutters for shingle granules, or look for patches of darker or inconsistent colors on your roof. These are signs that the granules have worn away.

4. The Flashing System is Cracked or Damaged

The flashing around skylights, chimneys and vents act as a seal for the roof’s seams. Cracks, breaks and damage in this area can lead to leaks.

If you live in an older home, there’s a good chance that the flashing is made of tar or cement. Upgrading to a metal flashing system will improve durability.

5. Moss is Growing on Your Shingles

Moss may be an indication of trouble. Just like fungi and mold, moss can be a sign of trapped moisture. If left unchecked, trapped moisture can damage a roof.

Moss can be removed with a stiff brush. But take the time to investigate the underlying issue. You may have a small leak, or your roof may be failing.

Regular care and maintenance of your roof can help extend its lifespan, but just like anything else in your home, it will need to be replaced at some point. Keep these five points in mind when considering whether your roof needs to be replaced.
